Abstract

A telecommunications switching system (1) has a switch unit (2) having switches (9) controlled by local modules (10). These modules implement instructions which are either in-build or are received from remote modules (20) on machines (6, 7, 8) which communicate via a central router (3). This allows almost unlimited processing scalability and versatility. An application object base (21) has an object corresponding directly to a local module (10) or a subset thereof and a signal base (22) provides signal-level commands understood by the local module (10). A signal transfer function (23) on the remote machine (6), and a signal transfer function (11) on the switch unit (2) provide for direct transfer of signals in both directions. There is no need to modify the local modules (10) as the signal transfer function (11) is addressable as a local module and the remote aspect of the interaction is transparent to the local modules (10).
